    • A contact system of a circuit breaker includes a fixed contact. The contact system also includes a moveable contact arm assembly comprising at least one moveable contact arm having a moveable contact thereon, the moveable contact arm moveable to define a closed condition and a blow open condition. The contact system further includes a carrier assembly operatively coupled to the moveable contact arm. The contact system yet further includes a latch plate operatively coupled to the carrier assembly. The contact system also includes a trip shaft operatively coupled to the carrier assembly, the trip shaft having a non-circular region defining an engagement surface disposed in contact with the latch plate in the closed condition. The contact system further includes a biasing portion of the moveable contact arm configured to rotate the trip shaft out of engagement with the latch plate and into the blow open condition.
    • 断路器的接触系统包括固定接点。 所述接触系统还包括可移动的接触臂组件,其包括至少一个可移动接触臂,所述至少一个可移动接触臂具有可移动接触,所述可移动接触臂可移动以限定闭合状态和打开状态。 接触系统还包括可操作地联接到可移动接触臂的载体组件。 接触系统还包括可操作地联接到载体组件的闩锁板。 接触系统还包括可操作地联接到承载组件的跳闸轴,跳闸轴具有限定在闭合状态下设置成与闩锁板接触的接合表面的非圆形区域。 接触系统还包括可移动接触臂的偏压部分,其构造成使跳闸轴与闩锁板脱离接合并进入吹气状态。
